As of 2015, there were over 75,000 elevators in New York City. The frequency table summarizes data on the number of elevators of
each type. How do you make a frequency graph to display the data? Photo included. Please answer, thanks!

Answer:
Please find attached the log graph of the count (frequency) of the elevator types
Step-by-step explanation:
The number of different elevators types = 9
The maximum count of an elevator type = 96,602
The minimum count of an elevator type = 45
The mean count or number of elevator per type = 8,454
The standard deviation of number of elevator per type = 20,599.6
Given the wide difference between the mean and the standard deviation, the values of the count or frequency can be converted into the equivalent ㏒₁₀ values to flatten the frequency bar chart or histogram as follows;
Type Count (f) ㏒₁₀ (f)
Passenger elevator 66,602 4.823487
Freight elevator 4,140 3.617
Escalator 2,663 3.425371
Dumbwaiter 1,143 3.058046
Sidewalk 943 2.974512
Private elevator 252 2.401401
Handicap lift 227 2.356026
Manlift 73 1.863323
Public elevator 45 1.653213
The information can then be easily graphically displayed.

Answer:
(B) At Maryland, the mean number of points per player per game is greater than the median number of points per player per game.
(D)The mean number of points per player per game is the same at all 3 schools.
Step-by-step explanation:
<u>Baylor University</u>
6 players who each score 12 points per game
6 players who each score 0 points per game.
The Scores are: 0,0,0,0,0,0,12,12,12,12,12,12
<u>University of Maryland</u>
1 player scores 58 points per game,
1 player scores 14 points per game,
The rest(10) of the players score 0 points per game.
The Scores are: 0,0,0,0,0,0,0,0,0,0,14,58
<u> Dartmouth College</u>
4 players score 5 points per game,
4 players score 6 points per game,
4 players score 7 points per game.
The Scores are: 5,5,5,5,6,6,6,6,7,7,7,7
The following applies:
(B) At Maryland, the mean number of points per player per game is greater than the median number of points per player per game.
(D)The mean number of points per player per game is the same at all 3 schools.
Given :
Liam has a bag of b beads.
He gives 20 beads to his sister.
He then makes 4 necklaces with the same of beads on each necklace using all of the remaining beads.
To Find :
Write an expression that represents the number of beads on each necklace.
Solution :
Number of necklace remains after giving 20 beads to his sister is ( b - 20 ).
Number of beads on each necklace using all of the remaining beads is :
Hence, this is the required solution.
